Tip & How-To about Home Security

How Does a Home Automation System Work?

Methods of Control

  • Components of a home automation system are controlled via various methods, depending on the manufacturer. Systems may be controlled wirelessly or may be hardwired. Wireless methods use radio frequencies like Bluetooth and infrared, while hardwired systems may use ethernet, phone cable, electrical wire or coax cable. Most systems use a mix of wired and wireless components.

Lighting

  • Lighting is handled by inline dimmers, lamp plug-ins and gas fireplace dimmers. Hardwired dimmers and lamp plug-ins are installed between the light and the power source. The dimmers regulate the amount of power sent to the light giving you the ability to adjust the brightness of the lighting. Fire place dimmers work the same way, they allow you to regulate the amount of gas released and control the brightness and mood your fireplace gives off.

Heating and Cooling

  • Replacing your current thermostat with a "smart" thermostat allows you to remotely program when your air conditioning or heating unit operates and what temperatures they maintain. led displaystransparent led screenThermostats can either be programmed to switch on or off at certain times or may be controlled through the internet via an ethernet connection. You can also control it wirelessly via RF signals.

Security

  • Security setups contain a base unit and any number of wireless and hardwired sensors for doors and windows. Sensors are made of two pieces that touch when the door or window is closed. But when the device is separated, by a door or window being opened, the electronic circuit is broken. The sensor reports the breach back to the base unit via radio frequencies. If the base unit is active when the breach occurs, it will sound an alarm and a phone line connection to dial pre-programmed contacts--such as emergency services or your cell phone.

Cameras, Surveillance and Driveway Reporters

  • If you have a driveway reporter, when something passes by and breaks its laser beam, alarm security systemthe length of the break and time of occurrence are reported back to a base unit inside your home via RF signals. Units detect the presence of people and vehicles but ignore animals. Cameras work similarly--they report video data back to a base unit via RF signals. Cameras may also use infrared technology for night vision or compacted circuitry for a smaller size. The base unit for the cameras sends video signals to a monitor, VCR or a hard drive.

autoplay CD DVD is lost and I can not repair it via control panel


OK taking the easy way out on this one. There 5 methods to fix this issue on the Microsoft Support site. Method 1 involves Easy CD Creator (probably not the issue) and method 5 is if you installed a new drive (probably not the issue). So I would try method 2-4 in order.

Sometimes it just easier to post a link to a fix than type out the whole thing. Hope this helps.

career in robotics


At my university, they offer a graduate program in robotic engineering. Here are the course requirements:

=================

RBE 1001. Introduction to Robotics (Formerly ES 2201).
Cat. I
Multidisciplinary introduction to robotics, involving concepts from the fields of electrical engineering, mechanical engineering and computer science. Topics
covered include sensor performance and integration, electric and pneumatic actuators, power transmission, materials and static force analysis, controls and programmable embedded computer systems, system integration and robotic applications. Laboratory sessions consist of hands-on exercises and team projects where students design and build mobile robots. Undergraduate credit may not be earned for both this course and for ES 2201.
Recommended background: mechanics (PH 1110/PH 1111).
Suggested background: electricity and magnetism (PH 1120/PH 1121), may be taken concurrently.


=================


RBE 2001. Unified Robotics I.
Cat. I
First of a four-course sequence introducing foundational theory and practice of robotics engineering from the fields of computer science, electrical engineering and mechanical engineering. The focus of this course is the effective conversion of electrical power to mechanical power, and power transmission for purposes of locomotion, and of payload manipulation and delivery. Concepts of energy, power and kinematics will be applied. Concepts from statics such as force, moments and friction will be applied to determine power system requirements and structural requirements. Simple dynamics relating to inertia and the equations of motion of rigid bodies will be considered. Power control and modulation methods will be introduced through software control of existing embedded processors and power electronics. The necessary programming concepts and interaction with simulators and Integrated Development Environments will be introduced. Laboratory sessions consist of hands-on exercises and team projects where students design and build robots and related sub-systems.
Recommended background: ES 2201/RBE 1001, ES 2501 (can be taken concurrently), ECE 2022.


=================


RBE 2002. Unified Robotics II.
Cat. I
Second of a four-course sequence introducing foundational theory and practice of robotics engineering from the fields of computer science, electrical engineering and mechanical engineering. The focus of this course is interaction with the environment through sensors, feedback and decision processes. Concepts of stress and strain as related to sensing of force, and principles of operation and interface methods for electronic transducers of strain, light, proximity and angle will be presented.
